GC97 DC 8-200V 20A/30A/50A/100A/150A/200A/300AVoltmeter Ammeter Car Battery Tester Coulometer Capacity Electricity Vol

Features:1. This instrument is a professional Coulometer. The basic function of the instrument is measurement. It must ensure the accuracy of measurement.2. The GC97 Coulometer uses a 22-bit AD high-precision independent sampling chip for voltage and current detection,Charging and discharging can be automatically identified.3. Charging can display the icon of power plug, the image is easy to understand, and the accumulative time of charging or discharging can be automatically calculated.The progress bar by 50 grids.The display screen adopts 8192 phase matrix LCD screen, and the display content is richer and more delicate than the fixed pen segment LCD screen.4. Wide operating voltage, suitable for all batteries. Independent power supply can measure 0-350V. At the same time, it has the function of temperature detection. When the ambient temperature exceeds 43 degrees, it will output alarm voltage signal.5. Diversified backlight function, can choose long bright, automatic, fixed shutdown. Alarm function. Voltage upper and lower limits, current upper limits. When qualified, the instrument output interface has high voltage signal output, which can read the instruments test data through the instruments TTL serial port output. (Need professional use, ordinary users please ignore.)6. Visual menu setting function. Easy to operate by looking at the screen prompt. Voltage and current can be easily corrected by software.Specifications:Operating Voltage: 8-200VWorking Current: 50A/100/20
